Thank you, Michael. In the first quarter of 2026, Calix delivered yet another quarter of record revenue of $280 million, marking a sequential increase of 3%, driven by continued strong demand for our platform. This quarter, we welcomed 14 new customers, reinforcing our ongoing efforts to grow our customer base, while supporting their expansion within the local communities they serve. Remaining performance obligations were $376 million, down 2% sequentially and up 11% year-over-year. The sequential decline related to a robust fourth quarter comparison and our focus on completing the migration of customers to the new third-generation platform. Current RPOs in the first quarter were a record $157 million, representing a 3% sequential increase and a 22% rise from the same period last year. We anticipate that RPOs will reaccelerate in the second half of 2026 as we gain momentum with Calix One, underscoring the strength of our business model as customers, focused on delivering exceptional experiences, adopt our platform, add incremental offerings and win new subscribers. Non-GAAP gross margin was 57.2%, down 80 basis points sequentially due to investment in our dual cloud environments as we migrated customers to our third-generation platform. Compared to last year, non-GAAP gross margin increased 100 basis points. Our balance sheet remains strong. DSO at the end of the first quarter was 36 days. Inventory turns remain steady at 3, reflecting continued inventory investments to address robust demand and building supply continuity, and we generated free cash flow in the quarter of $7 million. We also invested $171 million to buy back 3.3 million shares of our common stock at an average price of $51.34. Furthermore, the Board today authorized another $100 million to be added to this program. This investment speaks to our belief in the tremendous opportunity ahead and our commitment to creating lasting value for our stockholders. We finished the quarter with a strong cash and investment balance of $243 million. Turning to guidance. Our revenue guidance for the second quarter of 2026 is between $287 and $293 million, representing a 4% increase at the midpoint over the prior quarter. This reflects continued robust demand trends and a modest benefit from recapturing a portion of the higher memory costs via a memory surcharge. For the year, we expect revenue to grow between 15% and 20%. With demand/supply disconnect, so large related to memory components. There will inevitably be some companies that will come up short. Our first priority is to ensure that we have adequate supply such that our customers can continue to add subscribers and take market share. Our advanced purchasing had allowed us to avoid higher memory component costs during the first quarter. However, that advanced supply has run its course, and we now face market prices. We are partnering with our customers to share in the higher memory costs, by initiating a surcharge, albeit it is a partial cost recovery and without adding gross profit is one way we can help our customers in this unfortunate memory supply environment. Our gross margin guidance for the second quarter of 2026 is between 24 -- sorry, 54.25% and 57.25%. Reflecting the effects of higher memory component costs, the impact from surcharges and the customer and product mix. The decline in appliance gross margin is expected to be offset by improvement in software and service gross margin as the dual clog costs abate, and we optimize the current cloud environment. For the year, we expect our non-GAAP gross margin to decline between 50 and 150 basis points. For non-GAAP operating expenses, we forecast $128 million at the midpoint in the second quarter of 2026, which is a sequential increase of $1 million. This increase is mainly driven by our efforts to expedite AI functionality and enhancements to the Calix One platform. Importantly, we continue to expect to return to our target financial model for operating expenses by the end of 2026, improving our operating leverage and profitability. Tomorrow morning, we are excited to host our first Investor Day in 4 years at the New York Stock Exchange. The event will look -- will provide a look into our strategy, innovation roadmap and the long-term prospects that drive our confidence for the future. In addition, we will outline our key targets for growth, profitability and cash flow, giving investors benchmarks to track our progress and understand how we are positioning Calix for sustained success in the coming years. Nancy, let's open the call for questions.
